Anal–oral sex, also referred to or described as anal–oral contact or anilingus (from anus + lingus (Latin Lingere:to lick), also spelled analingus, is a form of oral sex involving contact between the anus or perineum of one person and the mouth (lips) or tongue of another. Non-clinical, slang terms include rimming, rim-job, salad tossing, butt licking and eating ass. It is performed by people of all sexual orientations. Depending upon the context in which it is performed, this sex act can either be used for personal pleasure among consenting parties or as a form of erotic humiliation.
Technique
Anilingus involves a variety of techniques to stimulate the anus including kissing, licking, and sliding the tongue in and out of the anus. Pleasure for the receiver comes from the sensitive nerve endings surrounding the anal opening, which are not typically stimulated by the tongue and lips.
Pleasure for the giver can come from various sources. Anilingus can satisfy both anal and oral fixations in the giver. Pheromones produced in and around the anus and genitals also may add to the pleasures the giver receives .
